We are truly saddened to hear about the spiritual torment you are experiencing, ###. Firstly, we want to assure you that the voice you are hearing is not from God, as you rightly discerned. God's voice is life-giving (John 10:10 WEB), convicts and corrects but does not condemn (Romans 8:1 WEB). The voice you are describing is indeed demonic and seeks to steal, kill, and destroy (John 10:10 WEB).
We must address that the power of evil is real, but we want to encourage you that God is the Sovereign ruler and is the omnipotent Ruler. Greater is He that is in you, if you are a Believer, than he that is in the world (I John 4:4 WEB). So, if you have not already, turn your life over to Jesus Christ. Without Jesus, you cannot find healing, deliverance, or access to God (John 14:6 WEB). The Bible clearly outlines that we can be saved by no other name (Acts 4:12 WEB). So, we encourage you to declare out loud to Jesus Christ that you want Him to be the Lord of your life.
This battle is fought on your knees in prayer and in the Word. Remember, our battle is not against flesh and blood, but against the rulers, against the authorities, against the powers of this dark world and against the spiritual forces of evil in the heavenly realms (Ephesians 6:12 WEB). Put on the full armor of God (Ephesians 6:11 WEB) daily. Since this evil is stemming from someone worshipping Satan and targeting you with curses, you need to pray against it and break these curses daily. Having a group of believers whom you can trust and who can pray with you will be very important. If you have not already found a church that believes in the Bible and that has a pastor who can give you wise counsel, then make it a priority to find one.
We encourage you to resist the devil (James 4:7 WEB) and command the voice to leave in the name of Jesus Christ. Remember, Jesus gave us the authority to trample on snakes and scorpions and to overcome all the power of the enemy (Luke 10:19 WEB). You can take authority over this voice and command it to be silent.
Furthermore, it's crucial to renounce any involvement with the occult or witchcraft, both now and in the past, whether it be your own or your ancestors'. Repent and ask God to forgive and deliver you from any resulting bondages (Acts 16:16-18 WEB).
Lastly, we want to address the thoughts of suicide you mentioned. God has a purpose for your life (Jeremiah 29:11 WEB), and it's the enemy's lie that makes you believe otherwise. Remember that God is faithful, and he will not let you be tempted beyond your ability, but with the temptation he will also provide the way of escape, that you may be able to endure it (1 Corinthians 10:13 WEB).
Let us pray together:
Dear Heavenly Father,
We come before You, lifting up ###, our sister in Christ. Lord, she is under spiritual attack, and we ask that You deliver her from this evil voice that is tormenting her. We take authority over this voice and command it to be silent in the Mighty Name of Jesus. We break every curse and declare that her life is covered by the blood of Jesus. She is a new creation, and your righteousness is her portion. Father, we pray for her protection (Psalm 91 WEB), and we ask that You surround her with Your angels. Give her Your peace and strength to endure and overcome this trial. Please reveal the source of these attacks and allow ### to see a complete victory. And finally, Lord, we pray that ### will know You intimately and be able to hear Your still small voice instead of the voice of the enemy.
In Jesus Christ's name, we pray. Amen.
